In the grinding process, the workpiece surface layer will be grinding wheel cutting force, the role of compression and friction. Especially for the latter role, the workpiece surface layer formed directional strong plastic deformation and hardening layers. The metamorphic layer necessarily affects the change of residual stress in surface layer.
(1) cold plastic deformation of layers
In the grinding process, every moment of wear particle is equivalent to a cutting edge. However, in many cases, before the cutting edge angle is negative, except for cutting role of wear particles, is to make the surface subjected to compression (plough), clear plastic deformation of workpiece surface layer. This deformation degree of deformation layer with the degree of grinding blunt grinding feed and grow larger.
(2) hot plastic deformation (or high-temperature deformation)
Grinding heat work surface to form the instantaneous temperature, makes a certain depth of sharp decline in surface layer of elastic limit, or even the extent of the loss of elasticity. Work surface layer on grinding force at this time, especially under the effect of compression and friction, cause freedom stretch, subject to limitations as base metal, the surface is compressed (plow), in surface layer caused by plastic deformation. High temperature plastic deformation in grinding process of the same cases, increased with the rise in surface temperature.
(3) work-hardening layer
Sometimes micro-hardness and metallographic law can be found, due to deformation of the surface layer hardness up.
Except for grinding, casting and heat treatment heat caused by surface decarburization layer, and later on the processing only if they have been fully in place, were left in the surface of the workpiece surface will cause softening modification, leading to early failure of 2318K+H2318-aligning ball skf bearings.
